Product Description
Eccentric Reducing Rubber Joint Overview
The eccentric reducing rubber joint features an offset design where the large-diameter flange centerline is offset from the small-diameter flange centerline. This unique structure accommodates pipeline misalignment and thermal expansion during diameter transitions, ensuring smooth fluid flow without significant pressure drop or turbulence.
